NOTE: GP Series switches are available with screw or solder terminals in U.S. or metric sizes.
*For solder terminals, replace the “T” in the third position of the part number with an “S” (e.g., GPTCND11 becomes GPSCND11).
†
For metric mounting, replace the “1” in the seventh position with a “0” (e.g., GPTCND11 becomes GPTCND01).
